names Horn onJJsH; se en j Gas-replicatin To all whom it may concern i Be it known that I, ERNEST HornCnUsH,

a subjectof the King of Great Britain, resid ing in Blckley, England, have inventedcer tain new and useful Improvements in and,

Relating to Gas-Producers, of whichthe fol-. lowing is a specification.

There is a type ofgas producer in which the producer shaft consists of an annular water chamber connected at, top by shorti water tubes with a second annular chamber, a

the whole being inclosed in a casing from which theproducer gas is withdrawn. In

such a construction the producer gas passesinto the casing between the said connecting '1 tubes, thus imparting much of its sensible 5 heat to the water circulatingfthrough the tubes from one annular chamber to the other.

The upper chambers being provided with the, usual appurtenances of a steam boiler, the

plant becomes a combined gas and steam generator in which overheating ofthe walls of the producer is avoided and the 'gas is partially cooled before it leaves the plant. 7

By my invention I am enabled to construct an improved producer of the type set forth i wherein the main difiiculty usual in such type, namely; the collection of dust between the water tubes and the consequent necessity for frequent cleaning, is largely overcome.

This object is attained by arranging the usual constructions, but less dust is carried it away in the gases which, under influence of the bafiies, undergoes sharp changes of di rection of travel and thereby to deposit the dust which is collected in the casing. The

spaces between the sets'of tubes also facilitate poking of the fuel in theproducer shaft by means of of the caslng.
